Collapse Twitch after channels that are streaming

### Description

I would like a feature to show all of the **Twitch channels that are currently streaming**, and collapse, allowing the user to press 'show more' to show the currently non-streaming channels.
Most of the infrastructure should already be implemented for this change!

It could be added as a new boolean, defaulting to false but can be configured to true. No downsides I can think of, although it might look a bit strange if there are currently no streaming channels, as the list would appear empty until 'show more' is pressed.
